Drumska strela – making parts of the rally car

As a sponsor of the Formula Student team of the Belgrade University, Voxellab committed making a large number of unique parts for the car competition. In addition to small parts such as elements of control, certainly the most conspicuous and the most interesting is a variable intake manifold completely made FDM 3D printing technology from multiple parts. Although made from completely organic bio-degradable plastic, this vital element that suffers extremely high structural stress due to drastic shift under pressure and overpressure, without damage to successfully complete the competition season 2014 Extreme operating conditions in terms of load, increased operating temperatures and moving parts are integrated once again demonstrated the usability of 3D printing technology in solving real problems. Combined with the short-term and lower cost of production, additive manufacturing is the natural choice for making highly specialized parts and elements.

To further optimized variable intake manifold, we used the possibility of FDM technology and made a special grid structure instead of solid walls meet the elements of the case, which has increased the elasticity of the structure and reduce the weight of the entire assembly for almost 60%.
